RECOMMENDED POSTER MATERIALS

To ensure best performance against condensation/moisture ingress in outdoor poster advertising, we recommend:

For 1-3 Months Life

Wet Strength, Water Resistant or Waterproof Paper (115-2ØØgsm) - Additives included during paper manufacture prevent the paper from breaking apart when in contact with moisture, ensuring it remains strong and stable. These are common specification for short to medium term poster campaigns and billboard advertising.

For 3 Months Life

Lamination – 'encapsulating a paper poster in thin sheets of clear plastic'. This is also the only means of creating posters for outdoor use when 'water-based' inks are used. Delivers reliable performance if the encapsulation is made to seal around the whole perimeter of the poster.

Printing onto Plastic – Synthetic Paper (8Ø micron polypropylene), sometimes termed 'Poly Poster', or 22Ø micron sheet PVC are cost effective alternatives for longer-life poster applications e.g. displaying a business service offer, restaurant menus or repeating seasonal promotions.
